“Compression ratio”, which is the ratio of the absolute discharge pressure to the absolute suction pressure, is an important concept for a refrigeration professional. Compressors are limited in the pressure differential that they can impose on a vapor. Screw compressors have the highest potential and can achieve compression ratios as high as twenty to one. […]
Anyone that has operated a refrigeration system knows that a significant amount of energy is required to run a compressor. “Heat” and “energy” are measured using the same units, and much of the electrical energy required by the compressor is transformed into heat energy in the refrigerant vapor. Think about it this way. When any […]
A savvy refrigeration professional will not only understand the vapor compression cycle, but will also know the “condition” of the refrigerant throughout the system. Let’s start with saturation. Whenever a substance changes from liquid to vapor or vice versa, it is said to be “saturated”. Additionally, a refrigerant is saturated when liquid and vapor coexist. […]
A “pumped overfeed” or “recirc system” is similar to the gravity-flooded system in that it utilizes a vessel that was not part of the DX system. In a pumped overfeed system, however, the vessel, often called a “recirculator”, is not located above the evaporator. In fact, the recirculator may be a long distance from the […]
